Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78628, here are decompositions:

  • 5 + 78623 = 78628
  • 59 + 78569 = 78628
  • 89 + 78539 = 78628
  • 131 + 78497 = 78628
  • 149 + 78479 = 78628
  • 191 + 78437 = 78628
  • 227 + 78401 = 78628
  • 281 + 78347 = 78628

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78628 first appears in π at position 84,302 of the decimal expansion (the 84,302ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
